Abstract (en)

[origin: WO2006061288A1] In a fuel system for a combustion engine, the fuel is delivered by a high-pressure fuel pump into a fuel pressure reservoir from which it enters at least one combustion chamber of the combustion engine via at least one injector. A value (pr_actual) is provided for depicting the actual pressure inside the fuel pressure reservoir. A pressure regulating device, which enables fuel to be discharged from the fuel pressure reservoir, is pilot-controlled by a pilot-control signal (I<SUB>DRV</SUB>) that is established while taking a set pressure (pr_set) inside the fuel pressure reservoir into account. The invention provides that when establishing the pilot-control signal (I<SUB>DRV</SUB>), a value for a quantity of fuel (q<SUB>DRV</SUB>) flowing through the pressure regulating device is taken into account.
